Human Aging Gene Found In Flies Scientists have discovered a fast and effective way to investigate important aspects of human aging: a gene in fruit flies that means flies can now be used to study the effects aging has on DNA. The researchers found that flies with damage to this gene share important features with people suffering from the rapid aging condition Werner syndrome.
Gene Linked To Alcohol And Cocaine Dependence The search for genes associated with alcohol dependence has recently been extended to the tachykinin receptor 3 gene, located within a broad region on chromosome 4q. Researchers have found that seven of the nine single nucleotide polymorphisms -- DNA sequence variations -- in the 3' region of TACR3 have a significant association with AD as well as cocaine dependence.
Groundbreaking Methodology For Identify Cancerous Cells Recognizing the distinction between healthy and cancerous cells has traditionally been up to the eye of highly-trained cytologists and pathologists. While the majority of the resulting diagnoses are accurate, new technology can enhance the accuracy and alleviate the physical strain on the human observer. Now scientists have developed an automatic method based on vibrational microspectroscopy that identifies the presence of metastatic cancer cells without the need for staining, and without human input.
